MCQ
In which one of the following species the central atom has the type of hybridization which is not the same as that present in the other three?
- A$SF_4$
- B$I_{3}^-$
- ✓$SbCl_5^{2-}$
- D$PCl_5$
✓
Answer
Correct option: C.
$SbCl_5^{2-}$
c
Molecules having the same number of hybrid orbitals, have same hybridisation and
Molecules having the same number of hybrid orbitals, have same hybridisation and
number of hybrid orbitals,
$H=\frac{1}{2}[V+X-C+A]$
where,
$\mathrm{V}=$ number of valence electrons of central atom
$X=$ number of monovalent atoms
$C=$ charge on cation
$A=$ charge on anion
$S b C l_{5}^{2}=s p^{3} d^{2}, P C l_{5}=s p^{3} d$
$S F_{4}=s p^{3} d, I_{3}^{-}=s p^{3} d$
